Sleep is just as important for health as breathing is for a human being. Without proper sleep, the body and mind cannot function at their best.
How Many Hours of Sleep Does a Person Need in 24 Hours?
Doctors generally recommend that adults should sleep at least 7 to 8 hours a day.
According to some research studies, for better performance and complete physical recovery, 8 to 10 hours of sleep can be highly beneficial.
Children and teenagers need more sleep than adults, usually around 9–12 hours daily.
Daytime Sleep vs. Nighttime Sleep
Nighttime sleep is the most beneficial.
The reason is that the human body’s biological clock (circadian rhythm) is naturally programmed to stay awake during the day and sleep at night.
Sleeping at night helps regulate hormones, refresh brain cells, and strengthen memory.
Daytime sleep (short naps) can also be helpful, but it is not a substitute for proper
nighttime sleep.
Why Night Sleep is Healthier?
The human body follows a natural rhythm known as the circadian rhythm. This biological clock is designed for us to be awake during the day and sleep at night. When you sleep at night, your body aligns with this natural cycle, leading to maximum benefits such as:
Better hormone regulation (especially melatonin and cortisol)
Improved brain cell repair and memory function
Stronger immune system
Healthier metabolism and better heart health
